Two live specifications, J247 and J257, built on opposite exam philosophies — not one qualification with two names.
Book a Free ConsultationOCR examines GCSE Biology through two separately-accredited specifications: Biology A (Gateway Science), code J247, and Biology B (Twenty First Century Science), code J257, both currently at Version 4.0 (August 2026) with no withdrawal notice on either. Gateway splits its four papers by topic group; Twenty First Century splits its four components by cognitive demand, Breadth against Depth. The two are not interchangeable, and most guides online only ever describe one.
Already know whether your child is on Gateway or Twenty First Century?
Our expert GCSE biology tutors build every OCR programme around the actual route — Gateway’s topic-based papers or Twenty First Century’s Breadth-and-Depth split — rather than a generic revision list that assumes there is only one exam.

OCR’s own specification documents name two entirely separate GCSE Biology qualifications, both live for the same series. Biology A, marketed as Gateway Science, carries the code J247 and Ofqual accreditation number 601/8589/2; Biology B, marketed as Twenty First Century Science, carries the code J257 and accreditation number 601/8506/5. Both specifications are dated Version 4.0, August 2026 — the same edition number, the same publication month — which rules out the possibility that one is simply an older printing of the other.
Neither route is being phased out. A full-text search of both specification PDFs for the word “withdraw” returns exactly one match in each document, and it is the identical sentence in both: a malpractice clause about the withdrawal of a candidate’s grade for misconduct, not a notice that the qualification itself is closing. That distinction matters because OCR is in fact winding down a different qualification at the same time — A-level Biology B — so a route disappearing from OCR’s catalogue is not a hypothetical concern, and checking for it is the only way to be sure both GCSE routes remain genuine live choices rather than one legacy route being phased out quietly.
Both covers also carry the same transition notice: as of September 2025, OCR’s own name is Cambridge OCR, and certificates from the summer 2025 series onward carry the new branding while exam papers continue to show “OCR” or “Oxford Cambridge and RSA Examinations” during the changeover. Both specifications state, in identical wording, that the qualification “is available in England”, directing readers to a separate Wales or Northern Ireland register for those jurisdictions — the same England-only default AQA and Edexcel state on their own GCSE Biology specifications.
OCR names its combined-science equivalents differently again: Gateway’s double award is Combined Science A, code J250, and Twenty First Century’s is Combined Science B, code J260 — both carrying the higher Version 5.0, confirming they are separately maintained documents rather than the Biology specifications repackaged. A parent who sees “OCR Combined Science” and assumes it maps neatly onto whichever Biology route their child sits is assuming a link OCR’s own documents do not draw, which is why our GCSE tuition begins with the specification a student is actually entered for.
Before citing anything from OCR’s website, this page ran a control test, and the result changes which OCR link is worth following. Three URLs on OCR’s /qualifications/ hub were fetched with a real browser user agent: the genuine Biology A page, the genuine Biology B page, and a deliberately invented URL for a qualification that does not exist. All three returned HTTP 200, all three were exactly 48,185 bytes, and all three were byte-for-byte identical — MD5 2f199808c8f0fc7347528bba0c5186df on every one. Searching the real Biology A page’s own HTML for the string “J247” returns zero matches. The page that is supposedly about Biology A does not mention it.
The same test on OCR’s /Images/ PDF route behaves the way a working website should: an invented PDF filename returns a genuine 404 at 47,413 bytes, while the two real specification PDFs return 200 with the correct file size and a proper application/pdf content type. So a link that opens a page under /qualifications/ proves only that a URL exists on OCR’s server, nothing about what the qualification actually contains; a link that opens a PDF under /Images/ is the one worth following. Every fact on this page is sourced to the specification PDFs for that reason — a reader checking any of them by clicking through to OCR’s HTML subject page will find a page that looks fine and says almost nothing.
Gateway Biology A is assessed by four written papers, two per tier. Papers 1 and 3 (Foundation and Higher) examine Topics B1 to B3 plus the practical-skills topic B7; Papers 2 and 4 examine Topics B4 to B6 plus B7, and assume knowledge of B1 to B3 already covered on the other paper. Each paper is 90 marks, runs 1 hour 45 minutes, and is worth 50% of that tier’s GCSE. Content itself is organised into six teaching topics — Cell level systems, Scaling up, Organism level systems, Community level systems, Genes, inheritance and selection, and Global challenges — plus B7 for practical skills, seven in total.
Twenty First Century Biology B does not split its papers by topic at all. Its four components — Breadth and Depth, at each tier — each draw on content from all eight of the route’s own teaching chapters, and are distinguished instead by cognitive demand. OCR’s own specification states that the Breadth paper “can assess content from across the whole specification” using short-answer questions only, with no extended response anywhere on it; the Depth paper also draws on the whole specification but must include “at least two extended response questions”, each “with a total of 6 marks”, and exists, in OCR’s own words, so learners “can demonstrate their depth of understanding of specific aspects of the content”. Each component is also 90 marks, 1 hour 45 minutes and 50% of that tier’s GCSE — identical arithmetic to Gateway, built on a completely different principle.
The two routes’ content maps do not line up topic-for-topic either. Twenty First Century organises its content into seven teaching chapters — including Chapter B7, “Ideas about Science”, which has no direct Gateway equivalent — plus Chapter B8 for practical skills, eight in total against Gateway’s seven. A tutor moving a student between routes cannot simply relabel Gateway’s topic numbers onto Twenty First Century’s chapter numbers and expect them to match.

Ofqual fixes the overall Assessment Objective weighting for GCSE science at 40% AO1 (knowledge and understanding), 40% AO2 (application) and 20% AO3 (analysis and evaluation), and both OCR routes hit that total exactly. How each route gets there is where they diverge. Gateway’s own assessment-objective table splits it identically across both of its papers: Paper 1 and Paper 2 each carry AO1 20%, AO2 20%, AO3 10%, adding to 50% each, so the same profile applies whichever paper a student is sitting.
Twenty First Century deliberately does not do this. Its own assessment-objective table weights Breadth at AO1 24%, AO2 18%, AO3 8%, and Depth at AO1 16%, AO2 22%, AO3 12% — both still summing to 50%, but distributed in opposite directions. Depth asks proportionally more application and analysis questions than Breadth does, which follows directly from what the two components are built to test: short-answer recall-and-application across the whole specification on Breadth, extended six-mark responses on Depth. Add Breadth’s 24/18/8 to Depth’s 16/22/12 and the total is 40/40/20 — the same fixed figure Gateway reaches with an identical split on both its papers, arrived at by two different routes.
| Paper / component | AO1 | AO2 | AO3 | Total |
|---|---|---|---|---|
| Gateway Paper 1 / Paper 2 (each) | 20% | 20% | 10% | 50% |
| Twenty First Century Breadth | 24% | 18% | 8% | 50% |
| Twenty First Century Depth | 16% | 22% | 12% | 50% |
My son was low in confidence after COVID and the gaps in learning were building up. Using this service helped plug those gaps, rebuild confidence, and improve his ability to learn properly again.
We arranged maths and English tuition ahead of GCSEs and both tutors were brilliant. My daughter's grades improved, and by results day she achieved two grades higher than in her mock exams.
I attended an English bootcamp with Leading Tuition and the experience was excellent. The teacher gave focused attention to the small group while keeping the lessons interactive and engaging.
OCR does not call its required practicals “required practicals” at all. Its own specifications use a different term throughout: Practical Activity Group, or PAG — not AQA’s “required practical”, not Edexcel’s “core practical”. Both GCSE Biology routes state the same compulsory minimum: “It is compulsory that learners complete at least eight practical activities”, derived from splitting the Department for Education’s “Biology, chemistry and physics GCSE subject content, July 2015” Appendix 4 into eight Practical Activity Groups.
The eight PAGs, read directly from Gateway’s specification, are: microscopy; testing for biological molecules; sampling techniques; rates of enzyme-controlled reactions; photosynthesis; physiology, responses and respiration; microbiological techniques; and transport in and out of cells. Comparing that list word for word against Twenty First Century’s own PAG table finds the same eight names, the same apparatus, and the same Appendix 4 attribution in both documents — a genuine check, not an assumption, and the answer is that this part of the two routes is identical rather than different.
What differs between GCSE and A-level is how the practical work is actually assessed. Both GCSE routes state that “no less than 15%” of the written-exam questions assess practical skills, and that is the entire mechanism — there is no separate certificate. A full-text search of both GCSE specifications for “Not Classified”, “CPAC” and “Practical Endorsement” returns zero matches in either document. That is a genuine absence, not an assumption, and it is a real contrast with our OCR A-level Biology page, where OCR’s own A-level specification describes a formal Practical Endorsement reported as a separate Pass or Not Classified result alongside the grade — a mechanism GCSE Biology simply does not have.
Both OCR GCSE Biology routes require at least 10% of marks to test GCSE-level (or above) mathematical skills, and both calibrate the difficulty identically, in wording confirmed against Gateway’s and Twenty First Century’s own specifications: Foundation-tier maths questions “will not be of a lower demand than that which is expected of learners at Key Stage 3”, and Higher-tier maths questions will not be lower than “question and tasks in assessment for the Foundation Tier in a GCSE qualification in Mathematics”. That is a floor on difficulty, not a topic list, and OCR’s wording is near-verbatim identical across both specifications — the same calibration device AQA uses on its own GCSE Biology specification, independently confirmed here in OCR’s own words for both of its routes.

Some awarding bodies state exactly what share of GCSE Biology marks is common to both Foundation and Higher tier. OCR does not. A full-text search of both specification PDFs for the phrasing Ofqual’s own regulatory floor uses — common questions “targeted at” the grades where the tiers overlap — returns zero matches referring to tier overlap in either document. The only section headed “Overlap” in either specification concerns overlap with Combined Science, Chemistry and Physics, not overlap between Foundation and Higher tier.
That is a genuine, checked absence, not an oversight in this page’s research: our sibling pages on AQA GCSE Biology and Edexcel GCSE Biology each report the tier-overlap figure their own board publishes. OCR’s own paper architecture is a plausible reason it publishes none — Gateway’s four papers and Twenty First Century’s four components are each independently graded documents, not Foundation and Higher versions of one shared paper, so there is no single board-published overlap figure of the kind its sibling boards state. Ofqual’s regulatory minimum for tier overlap still applies to OCR whether or not OCR publishes the resulting number.
OCR’s confirmed June 2026 grade boundaries, out of 180 marks overall, show Gateway’s Foundation tier at grade 5 112, grade 4 93, grade 3 68, grade 2 43 and grade 1 18. Twenty First Century’s Foundation tier, same series, same 180-mark maximum, reads grade 5 112, grade 4 91, grade 3 71, grade 2 52 and grade 1 33 — identical at the very top and increasingly different below it.
The clearest evidence that each route’s four papers are genuinely, independently graded — rather than a shared Foundation/Higher version of the same paper — sits one level down, at individual paper boundaries. Gateway’s Higher-tier Paper 3, out of 90 raw marks, needed 74 for a grade 9; Paper 4, the same 90 raw marks, same tier, same series, needed only 67. Twenty First Century shows the identical pattern: Higher-tier Depth needed 71 out of 90 for a grade 9, while Higher-tier Breadth, the same marks available, needed 67. Two papers worth exactly the same raw marks, in the same tier and series, carrying different boundaries — that is only possible if OCR grades each paper as its own document, which is exactly what both specifications describe. For the four-board comparison and the Higher-tier overall figures, see our GCSE Biology overview.

Two, and both are live for the same series. OCR’s own specification PDFs confirm Biology A (Gateway Science), code J247, Ofqual accreditation number 601/8589/2, and Biology B (Twenty First Century Science), code J257, accreditation number 601/8506/5. Both documents are dated Version 4.0, August 2026, and a full-text search of each for the word “withdraw” finds only a routine malpractice clause, not a withdrawal notice — unlike OCR’s A-level Biology B, which is being phased out. A statement of entry naming J247 or J257 points to a genuinely different paper structure, not a rebrand of the same qualification.
The exam philosophy, not just the name. Gateway Biology A assesses four papers split by topic group — Papers 1 and 3 cover Topics B1 to B3, Papers 2 and 4 cover B4 to B6. Twenty First Century Biology B instead splits its four components, Breadth and Depth, by cognitive demand: Breadth is short-answer only, Depth carries at least two six-mark extended-response questions, and both draw on content from all eight of the route’s teaching chapters rather than a topic subset. Each paper or component is 90 marks and 50% of that tier’s GCSE either way.
The overall total is, but the distribution is not. Both routes sum to Ofqual’s fixed 40% AO1, 40% AO2 and 20% AO3. Gateway splits that identically across its two papers, at 20% AO1, 20% AO2 and 10% AO3 each. Twenty First Century splits it unevenly: Breadth carries 24% AO1, 18% AO2 and 8% AO3, while Depth carries 16% AO1, 22% AO2 and 12% AO3 — the same fixed total reached by two deliberately different routes through it.
PAG stands for Practical Activity Group, OCR’s own term for what AQA calls a required practical and Edexcel calls a core practical. Both GCSE Biology routes require a minimum of eight, covering microscopy, testing for biological molecules, sampling techniques, rates of enzyme-controlled reactions, photosynthesis, physiology and respiration, microbiological techniques, and transport in and out of cells. Comparing both specifications’ PAG tables word for word finds the same eight names and the same Department for Education Appendix 4 sourcing in each, so this part of the two routes is identical rather than a point of difference.
No. Both GCSE routes assess practical skills only through the written papers, stating that “no less than 15%” of exam questions test practical skills, and that is the whole mechanism. A full-text search of both GCSE specifications for “Not Classified”, “CPAC” and “Practical Endorsement” returns zero matches. That is a real contrast with A-level Biology, where OCR’s own specification describes a formal Practical Endorsement, reported separately from the grade as a Pass or Not Classified result — GCSE Biology has no equivalent.
Because OCR’s /qualifications/ hub pages return the same generic shell for almost any URL on that route, real or not. A control test fetching the genuine Biology A page, the genuine Biology B page and a deliberately invented qualification URL found all three returning HTTP 200 at an identical 48,185 bytes, with zero mentions of “J247” anywhere in the body. The specification PDFs, under OCR’s /Images/ path, behave normally — a real one opens correctly and an invented filename returns a genuine 404 — which is why every figure on this page is sourced to a PDF rather than an OCR subject page.
Both specifications state, in identical wording, that the qualification “is available in England”, and direct readers to check the Qualifications in Wales Portal or the Northern Ireland Entitlement Framework separately for those jurisdictions. Neither document claims automatic availability outside England, and this wording is confirmed independently on both the Gateway (J247) and Twenty First Century (J257) covers — the identical Section 3f heading and sentence appear in both specification PDFs, word for word, rather than one route stating it and the other staying silent.
Out of 180 marks overall, Gateway’s Foundation tier needed 112 for a grade 5, 93 for a grade 4, 68 for a grade 3, 43 for a grade 2 and 18 for a grade 1. Twenty First Century’s Foundation tier, same series and same 180-mark maximum, needed 112 for a grade 5, 91 for a grade 4, 71 for a grade 3, 52 for a grade 2 and 33 for a grade 1 — identical at the top grade and increasingly different further down.
